Outstanding Matrimonial Attorney

I cannot recommend my matrimonial attorney, John P. Whiteman III, highly enough. From the very beginning, he was incredibly knowledgeable and took the time to clearly explain every step of the process so I always felt informed and prepared. His sensitivity and kindness during such a difficult and emo...tional time were unwavering. John consistently advocated for my best interests, provided professional and solid representation throughout the entire case, and made me feel supported every step of the way. Communication was always excellent — calls and emails were answered promptly and personally. I never felt left in the dark. His high standard of decorum and ability along with his compassion and dedication truly made a stressful situation easier to navigate. I am beyond grateful for John’s guidance ,support, outcome of my case and would absolutely recommend him to anyone in need of a matrimonial attorney.

John Whitemann is dedicated to his clients and always there to support and do the best for you in a diffucult part of your life

When I was going through my divorce, I had the privilege of meeting John Whitemann from Quatela Chimeri PLLC. The firm handled every step of the process with professionalism, and the staff was always kind, patient, and helpful whenever I called with questions. Choosing an attorney during such a di...fficult time is not easy, but the moment I met John, I knew he was the right person to help guide me through a part of my life I never imagined going through. John is the type of attorney who truly goes above and beyond to help his clients receive what they deserve in a divorce settlement. He always took the time to listen to my ideas, answer my questions, and—most importantly—be honest with me when difficult decisions or situations arose, even when things didn’t feel fair. I respected that honesty more than anything. John always treated me with respect, valued my thoughts and opinions, and responded promptly whenever I needed guidance. He never rushed conversations and always made sure I fully understood any paperwork or legal steps involved. One of the most meaningful things he did was after everything was finalized. He personally called me to check in and see how I was doing with accepting the finalization of my divorce. That level of care and professionalism meant so much to me, and it’s something I will always be grateful for.

Excellent Divorce Attorney

John worked with me through my divorce. He was extremely kind and helpful throughout the process. He kept me up to date on all progress throughout the divorce process and was very informative when I had questions. He advocated for my rights as a mother and am very grateful that I had him in my corner... during the divorce. Lastly, he helped us get to the finish line and get the papers signed in a timely manner and without going to court. Thank you for everything John!!

John Whiteman III

There were several extra difficulties in my contested divorce. They were all handled professionally, as quickly as possible and with great sensitivity and respect to the special circumstances. I was kept informed at all times. This resulted in a very fair outcome. I would highly recommend John W...hiteman III for any divorce or separation issue.

Honest, conscientious attorney...very rare

I gladly recommend John to anyone looking for an intelligent, honest, hard working divorce attorney. I did not hire John when my divorce proceedings began but was more "assigned" to him by a senior attorney at the firm. We had some very rough patches early on but in the end I find myself lucky and gr...ateful that the attorney I hired passed me on to John. Although we did not see eye to eye on everything, John clearly explained his logic for all of his decisions. He is honest and direct with his assessment of all the aspects of your case. Any time I called with issues or questions John was quick to reply. I have delt with other attorneys in the past that do not reply expediously or at all. You will never have that issue with John. Divorce is always a tough time for everyone involved. A good attorney will be honest, somewhat empathetic, and will fight for his client. I could not be happier with, or more highly recommend an attorney more so than I do John Whiteman.
